Z-axis linear rods for cartesian 3D printers are a must-have accessory, compatible with any bed size. Check out the pictures on my modified d-bot at www.thingiverse.com/thing:1001065. To get started, you'll need: 4 x Ø16 linear rods 2 x V-slots measuring 20x40 4 x Linear ball bearings LMEK16L 16 x Bolts M4x10 4 x Bolts M3x10 4 x Bolts M3x20 8 x M3 nuts Don't forget the standard M5 and square/t-nuts to secure the V-slots - you'll need 38 sets. When attaching the bearings with M4 bolts, it's advisable to pre-tap the holes, but you can also simply screw them in place if needed.
